Complain about noise coming from boozer, perhaps, punk style (7)
I believe the answer is:
mohican
'punk style' is the definition.
(punk hair style)
'complain about noise coming from boozer perhaps' is the wordplay.
'complain' becomes 'moan' (moan can mean to complain or whinge).
'about' means one lot of letters goes inside another.
'noise coming from boozer perhaps' becomes 'hic' (hic can mean a drunken hiccup).
'moan' placed around 'hic' is 'MOHICAN'.
(Other definitions for mohican that I've seen before include "type of cut" , "American native, 9 [ > HAIRCUT]" , "A Native American people" , "Hair style" , "Hairstyle with a tall, spiky wall of hair, shaved either side" .)
